Alex Szpakowski 4ef0d257e9 Added an optional font hinting argument to love.graphics.newFont / love.font.newRasterizer when loading TrueType fonts. Resolves issue #963.
Accepted values are "normal", "light", "mono", and "none".

Alex Szpakowski 8067d42df2 Canvases now have OpenGL ES support, updated Texture:setWrap to return false for repeat wrap modes in non-power-of-two textures if OpenGL ES 2 is used and the implementation doesn't have support for repeat on NPOT textures.

Alex Szpakowski 18ab3973e8 Added support for ETC2/EAC compressed textures. Changed the CompressedFormat enum names to capitalize the format names (e.g. "PVR1rgba4" instead of "pvr1rgba4".) Improved sRGB support for compressed textures.

Alex Szpakowski dfdd52e499 Added support for ETC1 and PVR1 compressed textures contained in KTX, PKM, and PVR files.
Most desktop graphics drivers don't support those formats.

Alex Szpakowski 3a51f0ad08 Changed the love.graphics internal code to always use a default shader when none is set externally, and replaced the deprecated OpenGL vertex attribute code with the equivalent generic vertex attribute functions.
This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.

Alex Szpakowski 8ffe610659 Added love.graphics.getStats. It returns a table with performance-related graphics statistics. Currently it contains these fields:
drawcalls: The number of internal draw calls made so far in the current frame.

canvasswitches: The number of times the active Canvas has been changed so far in the current frame.

texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.

images: The number of active Image objects.

canvases: The number of active Canvas objects.

fonts: The number of active Font objects.

Alex Szpakowski afc505e183 Added stack type enums to love.graphics.push (resolves issue #906.) Current enums are "transform" and "all". "transform" is the default (for compatibility.) When love.graphics.push("all") is used, love.graphics.pop() will restore all love.graphics module state to what it was when push was called.
Updated the graphics code to use a custom matrix stack rather than OpenGL1's APIs.

Alex Szpakowski 8483ea31a1 Changed love.graphics.newImage's optional second argument to be a table of flags. Current flags are 'mipmaps' and 'srgb'.
If mipmaps are enabled on image creation, the image will use the default mipmap filter (now 'nearest' by default.) Image:setMipmapFilter will error if the image was not created with mipmaps enabled.

Alex Szpakowski 408a593113 Added support for several specific Canvas formats. Also added love.graphics.hasCanvasFormat.
The list includes RGBA with 4-bit components, RGBA with 10-bit R, G, and B components and a 2-bit alpha component, RGB with 9-bit RGB components and a 5-bit exponent component (for HDR rendering), and several more.

Alex Szpakowski ce4fdf4ac9 Added sRGB (gamma-correct) support for Images, Canvases, and the main screen.
love.graphics.newImage(path, “srgb”) creates a new Image whose texels are treated as being in the sRGB color space, so they are linearized when drawing/sampling from the image.

love.graphics.newCanvas(w, h, “srgb”) creates a new Canvas whose texels are treated as being in the sRGB color space, so drawing to the Canvas does a linear->sRGB conversion (but blends linearly), and sampling from it (drawing it or using it in a shader) converts from sRGB to linear space.

The "srgb" window flag does the same as Canvases for the main screen.

Alex Szpakowski aa69a695d3 Canvases can now be used in SpriteBatches, ParticleSystems, and Meshes (resolves issue #782).
Canvases and Images are now subclasses of the new Texture class.
Added setTexture and getTexture methods for Meshes, ParticleSystems, and SpriteBatches (the old set/getImage methods are deprecated but not removed.)
Canvas texture coordinates are no longer flipped.

Alex Szpakowski 1e696c4505 Added Mesh objects and love.graphics.newMesh. Mesh objects are similar to Geometry but they're drawables (the relationship between meshes and images is the opposite of geometry and images.)
Removed Geometry objects and re-added Quads.

example:
local vertices = {{0, 0, 0, 0}, {100, 0, 1, 0}, {100, 100, 1, 1}, {0, 100, 0, 1}}
mesh = love.graphics.newMesh(vertices, image, "fan")
..
